Tampa, Florida-- UPDATE: Tampa Police officers have released additional information in relation to Tuesday's incident involving 41-year-old James Minyard, and the loss of his fingertips because of "fireworks".

A report sent Wednesday says a joint investigation by the FBI and ATF revealed Minyard had at least four homemade explosive devices within his home.

The investigation reportedly launched after a BP gas station employee called 911 around 3 p.m. Tuesday to report that Minyard had injured his hand with fireworks.

The gas station was located along the 6900 block of Nebraska Avenue, but officers found Minyard in the 900 block of Sligh Avenue.

As previously reported, officials noted that Minyard had black residue on his hands, and was transported to Tampa General Hospital because he was missing the the tips of his left middle and ring fingers.

Reports sent Wednesday say an immediate search of the area revealed two homemade explosive devices. The discovery sparked a search of Minyard's home, where Tampa Police, Tampa Fire Rescue, ATF and FBI agents say they found four more homemade explosive devices in a makeshift laboratory, and evidence of bomb blasts in his backyard.

After Minyard's release from Tampa General Wednesday morning, he reportedly admitted to building the devices to "simply prove he could," says the report.

Minyard has since been booked at the Hillsborough County Jail on six counts of manufacturing and possessing homemade explosive devices.
